A digital signal processor (DSP) is a specialized microprocessor chip, with its architecture optimized for the operational needs of digital signal processing. [ 1 ] : 104–107 [ 2 ] DSPs are fabricated on metal–oxide–semiconductor (MOS) integrated circuit chips.
The Super Harvard Architecture Single-Chip Computer (SHARC) is a high performance floating-point and fixed-point DSP from Analog Devices. SHARC is used in a variety of signal processing applications ranging from audio processing, to single-CPU guided artillery shells to 1000-CPU over-the-horizon radar processing computers. The original design ...
The processors have built-in, fixed-point digital signal processor (DSP) functionality performed by 16-bit multiply–accumulates (MACs), accompanied on-chip by a microcontroller. [1] It was designed for a unified low-power processor architecture that can run operating systems while simultaneously handling complex numeric tasks such as real ...
Hexagon is also known as QDSP6, standing for “sixth generation digital signal processor.” According to Qualcomm, the Hexagon architecture is designed to deliver performance with low power over a variety of applications. [3] [4] Each version of Hexagon has an instruction set and a micro-architecture. These two features are intimately related.
TriMedia is a Harvard architecture [citation needed] CPU that features many DSP and SIMD operations to efficiently process audio and video data streams. For TriMedia processor optimal performance can be achieved by only programming in C / C++ as opposed to most other VLIW/DSP processors which require assembly language programming to achieve ...
Detailed descriptions of the μPD7720 architecture are found in Chance (1990), [8] Sweitzer (1984) [9] and Simpson (1984). [10] Briefly, the NEC μPD7720 runs at 4 MHz frequency with 128-word 16-bit data RAM, 512-word 13-bit data ROM, and 512-word 23-bit program memory, which has VLIW-like instruction format, enabling all of ALU operation, address register increment/decrement operation, and ...
The TMS320 architecture has been around for a while so a number of product variants have developed. The product codes used by Texas Instruments after the first TMS32010 processor have involved a series of processor named "TMS320Cabcd", where a is the main series, b the generation and cd is some custom number for a minor sub-variant.
Motherboard of the NeXTcube from 1990 having a Motorola 68040 (25 MHz) and a digital signal processor Motorola 56001 with 25 MHz which was directly accessible via an interface. In most designs the 56000 is dedicated to one single task, because digital signal processing using special hardware is mostly real-time and does not allow any interruption.
